Auto Save saves the job files at a user-specified interval. To edit the properties of this feature, select Auto Save from the any of the Options menus. A check next to the command on the menu indicates that it is enabled.
Auto Save allows you to set the interval between saves from 1 and 60 minutes. By default, the programs automatically set the save interval to 5 minutes. It is recommended that this feature not be disabled, however, if you wish to turn off the Auto Save function, check the box next to Disable in the window above and press OK.
The Autosave.esw File
If for some reason Earthwork 4D is closed without using the Exit command from the File Menu, any data entered within the auto save interval, and since the previous Save, is automatically saved to a file called Autosave.esw. The Autosave-1.esw file is located in the current working directory. This file is only created if the amount of time that has passed is greater than both the Auto Save interval and if the amount of time since the last Save command was executed exceeds the autosave interval. If Earthwork 4D is closed using the Exit command, or a new job is opened from the file menu, any autosave file is deleted.
Recovering the File
When an Autosave-1.esw file has been created and Earthwork 4D has closed improperly, the Autosave-1.esw file automatically opens the next time Earthwork 4D is opened. If an autosave file is opened, be sure to Save the file and either change the name of the file or choose the previous version of that file and overwrite it.
